How change Location of Bones by Name in edit.mode?

hello everyone, im new here
i would like to change the head position of the bones by names

example:
clacicle_l
bpy.context.active_bone.head[0] = 3.782

clacicle_r
bpy.context.active_bone.head[0] = 2.500

I think the below script should provide enough of an example for you to follow.

import bpy
from mathutils import Vector

b_name = "forearm.L"
b_pos = Vector((1,1,1))
obj = bpy.context.active_object


# use selected active object if object is an armature
if obj.type == 'ARMATURE'and obj in bpy.context.selected_objects:
    arm = obj
else:
    arm = None

# set positoin of edit bone head
if arm:
    ori_mode = bpy.context.mode
    bpy.ops.object.mode_set(mode = 'EDIT')
    my_bone = arm.data.edit_bones.get(b_name)
    if my_bone:
        my_bone.head = b_pos
    bpy.ops.object.mode_set(mode = ori_mode)
else:
    print("No active armature")
